linux - how to find the target file's full(absolute path) of the symbolic link or soft link in python

Question

when i give ls -l /etc/fonts/conf.d/70-yes-bitmaps.conf

lrwxrwxrwx <snip> /etc/fonts/conf.d/70-yes-bitmaps.conf -> ../conf.avail/70-yes-bitmaps.conf

so for a symbolic link or soft link, how to find the target file's full(absolute path) in python,

If i use

os.readlink('/etc/fonts/conf.d/70-yes-bitmaps.conf')

it outputs

../conf.avail/70-yes-bitmaps.conf

but i need the absolute path not the relative path, so my desired output must be,

/etc/fonts/conf.avail/70-yes-bitmaps.conf

how to replace the .. with the actual full path of the parent directory of the symbolic link or soft link file.

Answer 1

os.path.realpath(path)

os.path.realpath returns the canonical path of the specified filename, eliminating any symbolic links encountered in the path.
